'''58P5H1V1''' is an unnamed [[c/5 diagonal]] [[spaceship]] discovered by [[Matthias Merzenich]] on September 5, [[:Category:patterns found in 2010|2010]]. In terms of its minimum population of [[:Category:patterns with 58 cells|58]] [[cell]]s it is the smallest known c/5 diagonal spaceship. It provides [[spark]]s at its trailing edge which can perturb [[glider]]s, and this property was used to create the first c/5 diagonal [[puffer]]s. These sparks also allow the attachment of tagalongs which was used to create the first c/5 diagonal [[wickstretcher]] in January [[:Category:patterns found in 2011|2011]].

The final step for a [[glider synthesis]] of this spaceship was found by [[Goldtiger997]] and [[Tanner Jacobi]] on April 2, 2020.<ref name="post93110" /> Goldtiger997 posted a complete {{gliders|220}} synthesis, including the base [[still life]], on the next day,<ref name="post93167" /> making 58P5H1V1 the first spaceship of its speed to be synthesized. Reductions to the synthesis have since been made.<ref name="post93256" /><ref name="post93279" />
